I have 10 questions to answer one of which is in this post but I dont see the answer JA: The Math Tutor can help you get an A on your homework or ace your next test. Tell me more about what you need help with so we can help you best. Customer: they are actually very similar to the post I entered not sure if you can see that JA: Is there anything else important you think the Math Tutor should know? Customer: its p values, normal distributions, samples and populations

This is the scenario. There is no such a thing as psychic capability. So imagine a computer calculating probabilities (making predictions). Now, my question is what are the odds of predicting an assassination, having the timing within two days, and having the place. The time span for possibly predicting that is four years. Now the trick of it I that because there is no such thing as psychic capability the computer has no idea it is trying to predict an assassination. All the computer is programmed to do is to turn out predictions - of any type. Theoretically the computer doesn't know there are only 3 variables. I would think one would have to limit the possible variables because if you figured100 possible variables the computer "could" PRODUCE in a prediction the odds would be pretty low. Then there is the question of how many variables the computer must take into account when CALCULATING the prediction. In the real world there would be millions if not billions of variables the computer would have to take into account when performing the calculations. Basically I am defining the null field with no psychic capability and everything left to random chances.

A researcher predicts that watching a film on institutionalization will change studentsâ attitudes about chronically mentally ill patients. The researcher randomly selects a class of 36 students, shows them the film, and gives them a questionnaire about their attitudes. The mean score on the questionnaire for these 36 students is 70. The score for people in general on this questionnaire is 75, with a standard deviation of 12. Using the five steps of hypothesis testing and the 5% significance level (i.e. alpha = .05), does showing the film change studentsâ attitudes towards the chronically mentally ill? 1.What does it mean to set alpha at .05? 2.What is your null hypothesis? Alternate hypothesis? 3.Is this a one-tailed or two-tailed hypothesis? 4.What is the critical z? 5.Calculate the obtained z. Do you reject or fail to reject the null hypothesis? 6.State in words what you have found. JA: I hope not. The Math Tutor can help you get an A on your homework or ace your next test. Is there anything else the Math Tutor should be aware of? Customer: no
